Improved mode of hanging and fastening doors



OFFICE.

CHARLES N. EARL, OF ELKVRIVER, MINNESOTA.

IMPROVED MODE OF HANGING AND FASTENING DOORS.

Specification forming part of Letters Patent No. 88,857, dated April 13, 1869.

Improved Mode of Hanging and Fastening Sliding Doors; and I do hereby declare that.

the following is a full and exact description thereof, reference being had to the accompa- -nying drawing, and to the letters of reference I marked thereon.

The nature of my invention consists in providing the upper part of a sliding door with levers and pulleys, or rollers, which levers and pulleys are used to raise the door from the oor, and support its Weight, so as to be easily opened and shut, and providing` the door with a fastening or latch, which securely1 fastens the door on being shut, and unfastens it by the same motion of the levers which raises the door to be opened.

To enable others to make and use my invention, I will proceed to describe its construction and operation.

I construct my sliding door in any of the known ways; but in order to obviate the (lifticulty of sliding a door which rests upon a shoe on the floor, or runs in a groove, or rests upon rollers running on a rail laid on the oor, or in grooves cut in the tloor, and to exclude wind and storm when shut, I use levers, either wood or iron, as shown at A in the accompanying drawing, which are held to the door B by a cleat secured to blocks just the thickness of the lever, and firmly screwed or bolted to the inside of the door, as at C.

Above the door, and twice its length, is a horizontal stick or joist, D, firmly nailed or screwed to the frame of the building, inside, E, in which a groove is cut to receive the upper edge of the door to keep it from falling in.

behind the cleats, so that upon moving the lever by its lower extremity to the right or left the projection presses against the cleat and block, bringing the pulley down on the rail, and the door is raised sufciently to clear the floor, and is easily opened or shut, as the case may be.

The fastening II consists of a horizontal piece of wood or iron behind the lever, secured at one end to the door by a screw or bolt, a,

(being kept in a horizontal position when the door is open or being shut by a pin or block, b, near the edge of the door,) extending past the edge of the door, so that when the door is shut a notch in its under side will catch on the pin c, securely driven into the door-frame. A movement of the lever to open the door will instantly raise the latch, by means of a pin, d,

kin the latch above its fastening to the door.

What I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement, upon a sliding door, of

two or more levers, with rollers, latch, and

connections, all operating in such a manner that the door is unlatched, raised, and slid back by the same movement of the longer lever, substantially as set forth.

Dated February 23,1869, at Elk River, Minnesota.
